sPECIFIOACLION forming part of Letters Patent No. 722,289, dated March10, 1903.

Application filed June 28, 1902. Serial No. 113,645. (No model.)

To all whmn it may concern:

Be it known that I, DANIEL BARR DON- NELLY, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certainnew and useful Improvements inRefuse- Burners; and I do declare the following to be a full, clear, andexact description of the in Vention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to refuse-burners.

In the natural-gas regions the disposition of light refuse-such aswaste-paper, &c.-is a matter of considerable concern; and the object ofthe present invention is the provision of a light, simple, andinexpensive refuse burner or furnace which will be of value moreparticularlyin situations--such, for instance, as in the natural-gasregions-where an ordidary furnace or burner is not available, althoughits use is not necessarily thus restricted.

The present invention is designed for the speedy and satisfactoryconsumption of light refuse and is intended to be of such form that itwill be readily portable.

The details of the invention are set forth fully hereinafter and thenovel features recited in the appended claims.

Figure 1 is an elevation of the burner, partly broken away. Fig. 2 is asection on line 2 2 of Fig. 1. Fig. 3 is a rear view of one of the legs.Fig. 4 is a perspective of one of the legs.

The shell or casing of the burner or furnace is preferablyof cylindricalform and of sheet metal, stovepipe-iron being well adapted for thispurpose. The legs 2 are in the same piece with the shell 1 and areformed by cutting out the lower portion of the sheet metal, and theselegs are strengthened by bending the inturned flanges 3 thereon, whichextend the entire height of the legs and are provided with the notchesor slits 4, all of which are in the same horizontal plane. A sheetmetaldisk 5 is received in the notches 4, and thus supported by the legs. Onthe upper ends 6 of the flanges 3 rests a circular grate 7, of anypreferred construction, which is held against displacement by the strips8, projecting inwardly from the inner wall of the shell 1, which areformed by cutting openings 9 in the shell and bending inwardly theportion of the shell throughout. The upper margin or end of the shell isprovided with raised portions or projections 10, and the cover 11 reststhereon, said cover being connected to the shell by a suitable hinge 12and being of greater diameter than the shell, so that it will overhangthe sides of the shell, as at 13, the object of which is to provide adeflector, so that the products of C0mbllSi3lOH--SL10II as sparks,charred pieces of material, &C.6S- caping through the slots or openingsl t will not float away and endanger surrounding property. A suitablehandle 15 is provided on the shell for carrying the furnace about fromplace to place.

It will be understood that the bottom or disk 5 is located a suitabledistance below the grate and provides ample draft-space through whichair may enter to pass up through the grate, while any one of theopenings 9 can be used for the ignition of the material to be consumedwithin the furnace, and the slots 1% provide for the escape of the smokeand also constitute an outlet for the air, and thus a perfect draft isbad.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a refuse-burner, the combination with a tubular shell, having legsextending below its lower edge, of a grate supported inside of saidshell at or near the line of its lower edge, and a bottom supported bysaid legs below the lower edge of said shell, whereby openings areprovided for the admission of air between said bottom and the lower edgeof said shell.

2. In a refuse-burner, the combination with a tubular sheet-metal shellhaving legs integral therewith and extending belowits lower edge, saidlegs having-their edges bent inwardly and provided with notches, of agrate supported inside of said shell near its lower edge, and a bottomhaving its edge received in said notches, below the lower edge of saidshell.

3. In a ref use-burner, the combination with a tubular sheet-metal shellhaving legs intogral therewith and extending below its lower edge, saidlegs having their side edges turned inwardly and provided with notches,of a grate resting on the upper ends of said inwardly-bent edges, and abottom having its edge received in said notches below the lower edge ofsaid shell.

4. In a refuse-burner, the combination with a shell or casing and legsformed of sheet metal, said legs having their side edges turned or bentinwardly, of a grate supported by said inturned portions of the legs,and members projecting inwardly from the shell or casing above the grateadapted to prevent upward displacement thereof.

5. In a refuse-burner, the combination with a shell or casing, of agrate supported therein and members projecting inwardly from the shellor casing above the grate and adapted to prevent displacement thereof,said members being formed by cutting or slitting the shell or casing andbending inwardly the cut portions of the shell or casing.

6. In a refuse-burner, the combination with a shell or casing and legsof sheet metal, said legs having their side edges bent inwardly andprovided with notches, of a bottom received in said notches, a grateresting on the upper ends of said inwardly-bent side edges andprojections above the grate which are struck inwardly from the walls ofthe shell or casing.

'7. In a refuse-burner, the combination with a shell or casing havingupwardly-extending portions at its top and provided with intermediatedownWardly-cut-out slots, constituting outlets, of a lid resting on theupwardlyextending portions and overhanging the sides of the shell.

8. In a refuse-burner, the combination with a body provided withinwardly-extending flanges 3 formed with notches 4, and with theinwardly-extending strips 8 above said flanges, of a bottom supportedwithin said notches, and a grate supported between said flanges andstrips.

In testimony whereof I affix my signature in presence of two witnesses.
